Description

Technical Field

[0001] The utility model relates to the technical field of dust removal on the surface of paper books, in particular to a dust removal structure for ancient cultural relic books that need to be deacidified. Background Art

[0002] Acidification of ancient cultural relics and books exists in every country and has attracted great attention. Deacidification of paper books has brought great challenges to cultural relics protectors. Existing technologies show that anhydrous liquid phase deacidification system has a good deacidification effect. Its basic principle is that the alkaline deacidification substance present in the anhydrous liquid phase enters the paper to effectively neutralize the acidic components. In the deacidification process, online monitoring of the concentration of deacidification substances is an important link to ensure continuous and efficient deacidification. However, due to the long-term storage of paper books, the dust deposited on the surface and the shedding of paper tissue will seriously affect the monitoring of the concentration of deacidification substances. Therefore, before formally deacidifying paper books, impurities such as dust on the surface must be removed.

[0003] Some existing dust removal principles are mostly based on electrostatic dust removal, spray dust removal and pump suction dust removal. The objects of dust removal are mostly air, exhaust gas or workshops. For impurities such as dust on the surface of paper books, there are some problems based on the above principles:

[0004] (1) Electrostatic dust removal can effectively remove dust, but it cannot remove the detached materials in the aged paper tissue;

[0005] (2) Spray dust removal is suitable for air dust removal;

[0006] (3) Pump suction dust removal will damage the paper due to the large suction force, which is time-consuming and labor-intensive, and it is not easy to combine dust removal and deacidification in the same system. Utility Model Content
